There is still an outstanding issue with the libc/libpthreads in
"testing" and "unstable" whereby threads are not properly reaped after
termination.
This causes processes to leak and eventually no more threads or
processes can be created.

I have 2 LX164's, and have been running the latest version of Etch
on both for months now. I run several different configurations on
each machine, for testing purposes. While most issues have gone away
with newer releases, one has remained persistent. The machines boot
normally, and seem to run normally for 10 to 40 minutes, but then
begin to produce the same error, no matter what I try to do.
